Description

  The present invention relates to a calling wireless terminal that calls a specific or unspecified called wireless terminal.

  At a store or the like, there are times when a customer or a store clerk who is asked for an explanation wants to call a store clerk in the vicinity. Patent Document 1 describes a wireless terminal that calls a nearby wireless terminal as much as possible by gradually increasing the output of radio waves for calling a wireless terminal possessed by a store clerk when calling a counterpart terminal.

JP 2008-85746 A

  When calling a clerk, there is a case where it is desired to give priority to the clerk in charge even if it is a little far away. However, the technique described in Patent Document 1 only calls a nearby clerk and cannot preferentially call a specific wireless terminal owned by the clerk in charge.

  An object of the present invention is to call a specific called radio terminal possessed by a salesclerk in charge preferentially, and when there is no response from the salesclerk in charge to the call, an unspecified subject held by a salesclerk other than the salesclerk. The object is to provide a calling radio terminal having a function of calling the calling radio terminal.

  A calling radio terminal according to the present invention includes a radio communication unit that transmits or receives a radio signal, a control unit that controls the radio communication unit, and a key input unit for calling, and a calling radio that calls a called radio terminal. A call ID registration means for registering a call ID (IDentification) of a specific called radio terminal or a called radio terminal group to be called, and a key operation for calling the called radio terminal by specifying the call ID. When the call is made, a specific call means for transmitting a radio signal related to the call including the call ID registered in advance in association with the key operation and a key operation related to the call not specifying the called radio terminal are performed. An unspecified calling means for transmitting a radio signal relating to a call that does not include a call ID or does not specify a called wireless terminal, and a response from the called wireless terminal Response receiving means for receiving the wireless signal, and the response receiving means transmits the wireless signal related to the response even if a predetermined time elapses after the specific calling means transmits the wireless signal related to the calling. If not received, the unspecified calling means is automatically activated.

  In the calling radio terminal according to the present invention, the specific receiving unit or the non-specific calling unit may transmit the wireless signal related to the call even if a predetermined time has elapsed after the response receiving unit When no signal is received, the radio wave intensity of the radio communication unit is increased and the radio signal related to the call is retransmitted.

  According to the present invention, the called radio terminal possessed by the clerk in charge is preferentially called, and when there is no response from the clerk in charge, the unspecified called radio terminal possessed by the clerk other than the responsible clerk is called. A calling radio terminal for calling can be provided.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings, taking as an example a case where a customer or a clerk in the store calls a predetermined clerk at a store.
FIG. 1 is a diagram for explaining the overall structure of a call according to the present invention. FIG. 2 is a functional block diagram of the calling radio terminal of the present invention. FIG. 3 is a functional block diagram of the called radio terminal. FIG. 4 is a flowchart for explaining the operation of the calling radio terminal. FIG. 5 is a flowchart for explaining the operation of the called radio terminal to be called.

FIG. 1 shows the positional relationship between the calling wireless terminal 1 existing in the store and the called wireless terminals 21, 22, 31, 32, 33. Reference numerals 4 and 5 denote areas where the calling wireless terminal 1 can call the called wireless terminal.
The area where the called radio terminal can be called depends on the radio wave intensity of the radio signal output from the call radio terminal 1, and the area 4 when the radio wave intensity is low and the area 5 when the radio wave intensity is high. Note that, here, in order to simplify the description, the radio wave intensity has two levels of weak and strong, but may be set to multiple levels of two or more levels.

  The called radio terminals 21, 22, 31, 32, and 33 are all terminals of the same hardware, but here the terminals 21, 22 are called radio terminals 31, 32, It is assumed that 33 is a called radio terminal possessed by a store clerk in charge of the B product.

  The calling radio terminal 1 is installed at a fixed location or is owned by a store clerk, and is called by a customer or a store clerk, so that the called radio terminal 2X (X 1 or 2) or 3Y (Y is any one of 1 to 3) or all terminals. Which group of the called radio terminal 2X or 3Y is called is specified at the time of the calling operation. If no specific group is specified, all called radio terminals are called. If only one device is registered as a specific group, it is possible to call a specific device.

  When the called wireless terminal 2X is specified as a specific terminal group during the calling operation, the calling wireless terminal 1 first outputs a wireless calling signal including a call ID corresponding to the called wireless terminal 2X with a low radio wave intensity. Send with. The inside (area 4) of the circle inside the two concentric circles in FIG. 1 is the callable area at this time, and the called radio terminal 2X does not exist in this area. For this reason, none of the called radio terminals 2X returns a response. When a predetermined time elapses without a response, the calling wireless terminal 1 increases the output radio wave intensity and transmits the wireless calling signal again. The inside of the circle outside the two concentric circles (area 5) is the callable area at this time. The called wireless terminal 21 responds when the calling wireless terminal 1 increases its output, and communication is established between the calling wireless terminal 1 and the called wireless terminal 21.

Next, when the called wireless terminal 21 is also outside the area 5 and there is no called wireless terminal 2X in the area 5 (not shown), both of the called wireless terminals 2X respond. Do not return. In this case, the calling wireless terminal 1 again transmits a wireless calling signal for calling an unspecified called wireless terminal without lowering the output radio wave intensity and designating the group of called wireless terminals.
Then, since the called wireless terminal 31 exists in the area 4, the called wireless terminal 31 responds and communication is established between the calling wireless terminal 1 and the called wireless terminal 31. Originally, I wanted to call a clerk in charge of A product, but I called a clerk in charge of B product nearby. As a result, the customer clerk in charge of the B product in the vicinity can follow the customer even if the sales clerk in charge of the A product calls NG.

  If there is no desired called wireless terminal in the vicinity, whether to call the desired calling wireless terminal preferentially or to call an unspecified nearby calling wireless terminal even if it is far is set. Or it can be selected by key operation.

  FIG. 2 is a functional block diagram of the calling radio terminal 1, in which 101 is a control unit, 102 is a key input unit such as a numeric keypad, function key, and selection key, 103 is a call ID registration unit, 104 is a call signal transmission unit, Reference numeral 105 is a wireless communication unit, 106 is an antenna, 107 is a response signal receiving unit, 108 is a display unit, 109 is an audio input unit, 110 is an audio output unit, and 111 is a power supply unit.

  In the call ID registration unit 103, the call ID of a called radio terminal possessed by a specific store clerk or a store group in charge is registered. The call ID is associated with the key operation content of the key input unit 102, and the call ID is selected by key operation. For example, pressing the function key 1 (not shown) can register the called radio terminal 2X, and pressing the function key 2 (not shown) can be registered as a call ID specifying the called radio terminal 3Y. The operation of each part will be described later with reference to a flowchart.

  FIG. 3 is a functional block diagram of the called radio terminal 2X or 3X, in which 201 is a control unit, 202 is a key input unit such as a function key operated when answering a call, 203 is a called ID registration unit, 204 is a response signal transmitting unit, 205 is a wireless communication unit, 206 is an antenna, 207 is a calling signal receiving unit, and 208 is a display unit for notifying the operator of a ringing sound, a screen display, or a vibrator. , 209 is an audio input unit, 210 is an audio output unit, and 211 is a power supply unit. The functional block configuration of the called radio terminal 2X or 3X is the same, and the ID registered in the called ID registration unit 203 differs depending on the group of the store clerk possessed. When this terminal receives a call radio signal that matches the call ID registered in the called ID registration unit 203, the terminal notifies the operator of the call and returns a response to the caller by the operator's response operation. . The call radio signal is received by the call signal receiving unit 207. If the call radio signal has no call ID or the call ID designates all terminals, the call radio signal registered in the called ID registration unit 203 is received. The called operation is activated regardless of the ID value. The operation of each part will be described later with reference to a flowchart.

  2 and 3, the function block inside the terminal is described with the calling radio terminal and the called radio terminal as dedicated terminals, respectively. However, the calling / calling function in which the radio calling function and the radio called function are integrated. It may be a dual-purpose wireless terminal. In this case, there is an effect that each clerk who owns the calling / called wireless terminal can call each other. In addition, although not shown in the figure, the same name part in FIGS. 2 and 3 can be shared by the calling / calling-use wireless terminal.

FIG. 4 is an operation flowchart of the calling radio terminal 1. The operation will be described below in conjunction with FIG.
The flow starts when the operator of the calling radio terminal 1 who desires to call calls the key input unit 102 (S401).
There are two types of call operations from the key input unit 102: specific group call and unspecified call (all terminal call). Although it is possible to call a specific called radio terminal, since this is equivalent to a specific group in which only one is registered, a call of one specific called radio terminal is also treated as a specific group call here.

When the data input from the key input unit 102 is a key operation for designating a specific group (S402, YES), it corresponds to the input key operation among the call IDs registered in the call ID registration unit 103 The call ID of the specified group is read and set as a call target in the call signal transmission unit 104 (S403).
If the data input from the key input unit 102 is not a key operation for designating a specific group (S402, NO), the call target is set as unspecified (all terminals) in the call signal transmission unit 104 (S404).

  The call ID registration unit 103 registers a call ID that identifies each group of called wireless terminals, and the correspondence between the call ID and key operation. The called wireless terminals can be grouped freely according to charge, affiliation, position, age, etc.

  The call signal transmission unit 104 generates a call signal including the set call ID, and the wireless call signal is transmitted with the minimum output radio wave intensity via the wireless communication unit 105 and the antenna 106 (S410).

  Next, the control unit 101 starts a timer (not shown) in the control unit (S411) and waits for a response signal from the called terminal via the response signal receiving unit 107 (S412). When a response signal is received (S412, YES), the other party's response is displayed and a call can be made via the audio input unit 109 including a microphone and the audio output unit 110 including a speaker (S450).

  If the response signal is not received even after waiting for a predetermined time (for example, 10 seconds) (S413, YES) and the previous transmission is not the maximum output (S414, NO), the control unit 101 outputs the radio wave intensity from the wireless communication unit 105. And the radio call signal from the call signal transmission unit 104 is retransmitted (S415).

  If the previous transmission is the maximum output in S414 (YES), the desired callee terminal does not exist in the callable area 5, so the process proceeds to S431. If the previous call target is a specific group (S431, YES), the process proceeds to S404, the call target is set to all terminals (S404), and the steps after S410 are repeated. Thereby, even when calling of a desired specific group fails, an unspecified called terminal in the vicinity can be automatically called.

  If the previous call target is not a specific group in S431 (S431, NO), since all the terminals have been called and there is no called terminal in the callable area, a message indicating that the call has failed is displayed. (S452), this flow ends (S460).

  FIG. 5 is an operation flowchart of the called radio terminal. The operation will be described with reference to FIG. This flow starts when the power is turned on (S501), and waits for reception of a radio paging signal (S502). When the wireless calling signal is received via the antenna 206, the wireless communication unit 205, and the calling signal receiving unit 207 (S502, YES), the control unit 201 analyzes the calling ID included in the wireless calling signal, and the ID is If it is a group belonging to the own terminal registered in the called ID registration unit 203 or a calling ID corresponding to all terminals, the called terminal is displayed (S503). The called display is ringing, screen display, vibrator, or the like, and the called mode selected by the operator in advance is set. Then, an internal timer (not shown) of the control unit 201 is activated (S510), and a response operation from the key input unit 202 by the terminal owner is waited for (S520).

When a time-out occurs (for example, 1 minute) without any response operation (S521, YES), the called display is stopped (S522), and this flow ends (S550).
If the operator operates the key input unit 202 in S520 (S520, YES) and the key operation is a response rejection operation (S530, YES), the called display is stopped (S522), and this flow ends. (S550).

This response refusal operation is an operation for stopping the called display such as ringing when the store clerk who owns the called wireless terminal is in service. If the response refusal operation is not performed, the called display continues until time-out in S521.
When the key operation is a response operation for responding to the call (S530, NO), the control unit 201 controls the response signal transmission unit 204 and wirelessly transmits the response signal via the wireless communication unit 205 and the antenna 206. Transmit (S531). Then, the called display is stopped (S532), and it is displayed that the call state has been established, and the call processing via the voice input unit 209 and the voice output unit 210 is started (S533). When the call ends (S534, YES), this flow ends (S550).

  Note that the above-mentioned call may not be a two-way simultaneous call, but may be a one-way call such as “calling” from the called party to the calling party, or an alternate call in which the calling party and the called party speak alternately. .

  By the way, as means for including the call ID in the radio call signal, if the radio call signal is an analog signal, the radio call signal may be modulated by the call ID. If the wireless call signal is a digital signal, a call ID as digital data may be embedded in a predetermined information field.

  As described above, according to this embodiment, it is possible to call a store clerk near the caller as much as possible in a specific group such as a specific product person in a simple operation, and a specific product person in charge within the callable area. Even if it does not exist, it is possible to call a nearby store clerk other than the person in charge of the specific product, so that it is possible to appropriately follow the caller.
